  • Bamboo salt, a Korean folk medicine, is prepared with solar salt (sea salt) and baked several times at high temperatures in a bamboo case. In this study, we compared the preventive effects of bamboo salt and purified and solar salts on hepatic damage induced by carbon tetrachloride in Sprague-Dawley rats. Compared with purified and solar salts, bamboo salts prevented hepatic damage in rats, as evidenced by significantly reduced serum levels of aspartate aminotransferase, alanine aminotransferase, and lactate dehydrogenase (P < 0.05). Bamboo salt (baked $9{\times}$) triggered the greatest reduction in these enzyme levels. In addition, it also reduced the levels of the proinflammatory cytokines interleukin (IL)-6, interferon (IFN)-${\gamma}$, and tumor necrosis factor (TNF)-${\alpha}$. Histopathological sections of liver tissue demonstrated the protective effect of bamboo salt, whereas sections from animals treated with the other salt groups showed a greater degree of necrosis. We also performed reverse transcription-polymerase chain reaction and western blot analyses of the inflammation-related genes iNOS, COX-2, TNF-${\alpha}$, and IL-$1{\beta}$ in rat liver tissues. Bamboo salt induced a significant decrease (~80%) in mRNA and protein expression levels of COX-2, iNOS, TNF-${\alpha}$, and IL-$1{\beta}$, compared with the other salts. Thus, we found that baked bamboo salt preparations could prevent $CCl_4$-induced hepatic damage in vivo.

  • The mammalian sirtuin family (SIRT1-SIRT7) has shown diverse biological roles in the regulation and maintenance of genome stability under genotoxic stress. SIRT7, one of the least studied sirtuin, has been demonstrated to be a key factor for DNA damage response (DDR). However, conflicting results have proposed that Sirt7 is an oncogenic factor to promote transformation in cancer cells. To address this inconsistency, we investigated properties of SIRT7 in hepatocellular carcinoma (HCC) regulation under DNA damage and found that loss of hepatic Sirt7 accelerated HCC progression. Specifically, the number, size, and volume of hepatic tumor colonies in diethylnitrosamine (DEN) injected Sirt7-deficient liver were markedly enhanced. Further, levels of HCC progression markers and pro-inflammatory cytokines were significantly elevated in the absence of hepatic Sirt7, unlike those in the control. In chromatin, SIRT7 was stabilized and colocalized to damage site by inhibiting the induction of γH2AX under DNA damage. Together, our findings suggest that SIRT7 is a crucial factor for DNA damage repair and that hepatic loss-of-Sirt7 can promote genomic instability and accelerate HCC development, unlike early studies describing that Sirt7 is an oncogenic factor.

  • This study was conducted to retrospectively evaluate the pattern of contrast enhancement with SonoVue on gray-scale ultrasonography of hepatic angiomyolipoma (HAML). Imaging features of 33 pathologically proven HAML lesions in 33 patients who underwent baseline ultrasound and contrast-enhanced ultrasonography (CEUS) were assessed retrospectively. All lesions were enhanced in the arterial phase and showed whole-tumor filling in. Thirty-two of 33 (97%) lesions showed early positive enhancement in the arterial phase. Twenty-three of these exhibited isoechoic or hyperechoic features in the portal phase. HAML demonstrate characteristic manifestations with SonoVue-enhanced real-time gray-scale ultrasonography.

  • Previously, a flavonoid fraction, which consisted mainly of protocatechuic acid, fustin, fisetin, sulfuretin, and butein, here named RCMF $({\underline{R}}VS\;{\underline{c}}hloroform-{\underline{m}}ethanol\;{\underline{f}}raction)$, was prepared from a crude acetone extract of Rhus verniciflua Stokes (RVS) which is traditionally used as a food additive and as an herbal medicine. In this study, we evaluated the effects of RCMF on the antioxidant defense system using embryonic normal hepatic cell line (BNL CL.2) and its SV40-mediated transformed cell line (BNL SV A.8). This study demonstrates that RCMF selectively stimulated the antioxidant defense system of normal cells, as BNL CL.2 cells proved to be more sensitive to RCMF-mediated increases of superoxide dismutase, catalase, glutathione, and glutathione reductase than BNL SV A.8 cells. In particular, RCMF caused a significant increase in the malonaldehyde content of BNL SV A.8 cells, which is believed to be closely associated with cytotoxicity of RCMF and RCMF-mediated growth inhibition. Collectively, our findings suggest that the flavonoid fraction, RCMF, selectively stimulates the antioxidant defense system in normal rather than hepatic tumor cells.

  • Pure primary hepatic rhabdomyosarcoma in adult is very uncommon. There have been only five previous case of primary rhabdomyosarcoma of the adult liver. A case of hepatic rhabdomyosarcoma was diagnosed in a 52 year-old female. She was admitted to the hospital due to the epigastric pain and weight loss. A CT scan of the abdomen showed a large hypodense mass with focal calcification occupies most of the both lobes of the liver. The liver biopsy showed massive liver tumor composed entirely of oval shaped cells showing light microscopic and immunohistochemical evidence of rhabdomyoblastic differentiation. We report a case of hepatic rhabdomyosarcoma with review of literature.

  • Purpose: To assess the effect and safety of lobaplatin combinated floxuridine /pirarubicin in transcatheter hepatic arterial chemoembolization(TACE) of unresectable primary liver cancer. Patients and Methods: TACE combined with the chemotherapy regimen was used to treat 34 unresectable primary liver cancer patients. DSA/MRI/CT/blood routine examinations were used to evaluate short term activity and toxicity after 4-5 weeks, the process being repeated if necessary. Results: Among the 34 cases, 1 (2.9%) showed a complete response, 21 (61.7%) a partial response, 8 (23.5%) stable disease, and 4 progressive disease, with a total effective rate of 67.6%. The content of alpha fetoprotein dropped by over 50% in 20 cases (58.8%). The rate of recovery was hepatalgia (88.2%), ascites (47.1%), appetite (55.9%), Performance Status(30.4%). The median follow-up time (MFT) was 281 days (63-558 days), and median progression-free survival was 118.5 days (95%, CI:88.8-148.2days). Adverse reactions (III-IV grade) were not common, with only 4 cases of vomiting and 2 cases of thrombocytopenia (III grade). Conclusions: Lobaplatin-based TACE is an effective and safe treatment for primary liver cancer.

  • A hepatic hemangioma is the most frequent benign liver tumor. Once rupture occurs, the bleeding can barely be controlled by using conservative management or endovascular treatment. We report a case of traumatic hepatic hemangioma rupture. A 60-year-old man was referred to our hospital under cardiopulmonary cerebral resuscitation (CPCR). CPCR was continued for 16 minutes after his admission to the emergency room (ER). Computed tomography (CT) showed fluid accumulation in the peritoneal cavity with active contrast extravasation in the left lateral segment of the liver. Percutaneous transarterial embolization and massive transfusion were carried out. Embolization did not stop the bleeding, we decided on an exploration and then resected the lateral segment of the liver to control the bleeding. The specimen showed a ruptured hemangioma in the liver segment.

  • Although hepatic microcirculatory dysfunction occurs during endotoxemia, the mechanism responsible for this remains unclear. Since Kupffer cells provide signals that regulate hepatic response in inflammation, this study was designed to investigate the role of Kupffer cells in the imbalance in the expression of vasoactive mediators. Endotoxemia was induced by intraperitoneal E. coli endotoxin (LPS, 1 mg/kg body weight). Kupffer cells were inactivated with gadolinium chloride ($GdCl_3$, 7.5 mg/kg body weight, intravenously) 2 days prior to LPS exposure. Liver samples were taken 6 h following LPS exposure for RT-PCR analysis of mRNA for genes of interest: endothelin (ET-1), its receptors $ET_A$ and $ET_B$, inducible nitric oxide synthase (iNOS), heme oxygenase (HO-1), and tumor necrosis factor-$\alpha$ (TNF-$\alpha$). mRNA levels for iNOS and TNF-$\alpha$ were significantly increased 31.8-fold and 26.7-fold in LPS-treated animals, respectively. This increase was markedly attenuated by $GdCl_3$, HO-1 expression significantly increased in LPS-treated animals, with no significant difference between saline and $GdCl_3$ groups. ET-1 was increased by LPS. mRNA levels for $ET_A$ receptor showed no change, whereas $ET_B$ transcripts increased in LPS-treated animals. The increase in $ET_B$ transcripts was potentiated by $GdCl_3$. We conclude that activation of Kupffer cells plays an important role in the imbalanced hepatic vasoregulatory gene expression induced by endotoxin.

  • A case of hepatic hemangioma is presented in which blood pool imaging by $^{99m}Tc$-HSA provided a definite diagnostic clue. Cavernous hemangiomas are the most common benign tumor of the liver. But the majority of them are asymptomatic and are found incidentally at laparotomy or autopsy. Selective hepatic arteriogrophy has been the most helpful technique for the preoperative diagnosis. Recently radioisotope scan and ultrasonogram proved to be a new, definite and non-invasive diagnostic procedure.

  • Primary liver tumors are uncommon in childhood, with a relative frequency of 3 % of all childhood tumors. Seventy-three cases of pediatric primary liver tumors operated on at single institution between 1986 and 2002 were reviewed. Malignant tumors included 37 cases of hepatoblastoma, 11 hepatocellular carcinomas, 6 undifferentiated (embryonal) sarcomas, and 1 mixed germ-cell tumor. Benign tumors constitute only 24.6 % of liver tumors, including 7 hemangioendotheliomas, 5 mesenchymal hamartomas, 3 congenital cysts, and one each with focal nodular hyperplasia and hemangioma. The common presenting clinical features were abdominal mass or abdominal distension. Anatomical hepatic resections were carried out in 38 cases, and nonanatomical resections in 34 cases. One patient died of a direct result of hepatic resection (1.4 %). The complication rate was 16.4 %.
